With over 10 million customers in 120 countries and 80,000 products in its range, Thomann GmbH is one of the world's highest-grossing mail-order companies for musical instruments, lighting, and sound equipment. What began in 1954 with company founder Hans Thomann Senior as a music shop in the living quarters of the family farmhouse is today a champion in the dynamically growing e-commerce sector. Deeply rooted in the Steigerwald region of Upper Franconia and run as an independent family business, 1,400 employees are responsible for Thomann's success. For Managing Director Hans Thomann Junior, despite all the changes, one of his father's maxims remains the most important foundation of the company: "Our customers determine our actions – we must listen to them and learn from them." A significant contribution to this success-determining foundation is made by the customer dialogue of the company's own call center with its 250 employees: Thomann Customer Service handles all requests related to orders, technical questions, and service in 19 languages ​​via telephone, email, or chat.

Since 2017, the Thomann call center, along with its associated back office and accounting department, has been equipped with direct room humidification. The system uses the Draabe Nanofog humidification system from Condair Systems. This system consists of 46 small jet humidifiers installed directly in the open-plan offices, which emit a fine mist as needed. Humidity is regulated by digital room sensors, ensuring a constant relative humidity of 40 percent year-round. For Alexander Schell of Thomann's construction department, guaranteed hygiene and ease of maintenance were the deciding factors in choosing the humidification system: "I was particularly impressed by the integrated water treatment of the Draabe system, which guarantees that only purified and germ-free water is used. Furthermore, we as users don't have to worry about maintenance." The multi-stage water treatment system is housed in portable containers, which are exchanged every six months by the manufacturer for fully serviced and cleaned systems as part of their regular maintenance service. Operational safety and hygienic performance are certified by the German Social Accident Insurance (DGUV) and the Association of German Engineers (VDI) and are regularly recertified on-site for installed systems. The system's integrated water treatment is housed in portable containers, which are exchanged every six months as part of the manufacturer's standard service for fully serviced and cleaned units.
